Diesel Exhaust After-Treatment by Silicon Carbide Fiber Filter
To reduce particulate matter (PM) in diesel exhaust gas, a diesel particulate filter (DPF) has been developed. The thermal durability of existing platinum catalyst-supported DPFs is inadequate. We are focusing on a non-catalytic after-treatment of silicon carbide (SiC) fibers with highly thermal durability. In this study, we simulated the processes of soot deposition and oxidation. Results show that even in exhaust gas without soot, a complex flow pattern is observed. The porosity of the filter is not constant along the flow direction, and the pressure gradient varies. The friction factor is slightly larger than the predicted value by the empirical equation in uniform porous media flow. Since the soot deposition occurs inside the filter, the depth filtration by SiC fibers was confirmed. In addition, the effects of filter temperature and oxygen concentration are clearly revealed. That is, comparing the oxidation at 700 °C, the deposited soot amount at 1200 and 1400 °C is decreased by 60% and 92%, respectively. Raising the oxygen concentration from 10% to 20% increases the oxidation efficiency from 42% to 64%. Although more work is needed over a wide range of operating conditions, a combination of these two parameters is important to achieve the non-catalytic exhaust after-treatment.journal articl
新潟水俣病発生企業立地地域における経済的影響関係について
To Take up Showa Denko Kanose factory and Kanose-cho that became the origin of Minamata disease as a model case,The number of employees and the sales amount of the Kanose factory shows a negative coefficient of correlation. The cause is because productivity improved due to capital spending. But it is hard to say what there was the economic effect to the area in the employment side by the factory operation unconditionally. It is thought that increase of the property taxes and the employer contribute to regional economy as the main constituent of consumption. It is estimated that there was a positive effect for a town. As for the effect, a factory was closed because of pollution outbreak, The population of Kanose-cho decreased, too.departmental bulletin pape

The genomic data set thus obtained contained 26,140 entries for and 49,472 entries for . For each species 100 independent randomised data sets were generated by reshuffling the nucleotide sequence of each entry. (b) screening using a CRE-specific frequency matrix. A positive hit was recorded if the matrix score reached a 95% cut-off threshold. (c) Determination of the distance of an element to the ATG. In the illustrated example d1 and d3 are the distances to the ATG for the elements localized on the [+] strand; d2 is the distance to the ATG for the element localized on the [-] strand. (d) Gap length between elements. In the example above Δ1 is the gap between two -oriented CREs (in this case [+/+]), and Δ2 and Δ3 are gaps between two -oriented CREs [-/+] and [+/-], respectively
